South Korean scientists built an air source heat pump integrated with a photovoltaic thermal unit that can reportedly achieve an average heating and cooling coefficient of performance (COP) of 3.54 and 3.31, respectively. The system is also claimed to be 44% cheaper than ground source heat pumps combined with PVT energy.Researchers at the Pusan National University in South Korea have designed an integrated system based on a photovoltaic-thermal (PVT) unit and an air source heat pump (ASHP) for deployment in zero-energy buildings (ZEBs) with limited space. In such buildings, the total sum of annual ...Den vollständigen Artikel lesen ...
